AI Article Synopsis
- The geriatric nutritional risk index (GNRI) is utilized to assess nutrition in hemodialysis patients, and simplifying its calculation can improve screening efficiency for malnutrition and mortality risk.
- A study evaluated 218 Japanese patients on hemodialysis, using a simplified version (sGNRI) based on serum albumin and body mass index, finding that lower sGNRI scores indicated higher mortality risk during a median follow-up of 4.4 years.
- The simplified GNRI is found to be as effective as the original version in identifying malnutrition and predicting mortality risk in hemodialysis patients.
Article Abstract
Introduction: The geriatric nutritional risk index (GNRI) is a widely used tool for nutritional assessment in patients receiving hemodialysis. The simplification of the GNRI calculation would be more useful for easier screening of malnutrition and for providing an intuitive stratification of mortality risk.
Methods: We retrospectively evaluated 218 Japanese patients receiving maintenance hemodialysis at two hemodialysis centers. The primary outcome was all-cause mortality. The main exposure was a simplified GNRI (sGNRI) calculated as follows: sGNRI = serum albumin (g/dL) + 0.1 × body mass index (kg/m ).
Results: During the median 4.4-year follow-up, 56 patients died. Multivariable-adjusted Cox proportional hazard risk models showed that patients with a lower sGNRI showed a significantly increased mortality risk. No significant difference was observed between the original GNRI and sGNRI regarding mortality predictability.
Conclusion: sGNRI is as useful as the original GNRI for screening for malnutrition and stratifying hemodialysis patients at increased mortality risk.
